Dynalco Magnetic Pickups with CSA & ATEX Approvals for use in industrial applications
Dynalco magnetic pickups convert mechanical motion to ac voltage without mechanical linkage or external power. These self-contained transducers produce a magnetic field which, when altered by a moving ferrous object, generates an ac voltage. It assumes a material that is attracted to a magnet, such as the pole piece of a magnetic pickup.
When the pickup is mounted in proximity to the teeth of a gear on a rotating shaft, the generated voltage has a frequency in direct proportion to RPM. Although a gear is preferable, a proper signal may be derived from evenly spaced screws, holes, or flats on a rotating ferrous shaft, or by using Dynalco’s exclusive TT-100 Tach Tape, especially designed for smooth ferrous or nonferrous shafts.
